Enum ProgramEdit 

pub enum ProgramEdit {
    Insert {
        index: usize,
        id: Option<String>,
        operation: PartOperation,
    },
    Update {
        id: String,
        operation: PartOperation,
    },
    Remove {
        id: String,
    },
    Move {
        id: String,
        index: usize,
    },
    Replace {
        program: Program,
    },
}

A change to a Program. Every edit of a program — whoever makes it — is one of these, applied by Program::update.

Steps are addressed by id, not position, so an edit means the same thing however the steps around it have moved. Serializes as, e.g., {"edit": "update", "id": "box", "operation": "extrude", "args": {...}}.

Variants

Insert

Insert operation as a new step at position index (the end, if it is the number of steps), with the id id — or, if that is None, a fresh one derived from the operation (see Program::fresh_id).

Fields

index: usize

id: Option<String>

operation: PartOperation

Update

Give step id a new operation or new arguments, in place.

Fields

id: String

operation: PartOperation

Remove

Remove step id. Steps that referred to what it built fail from then on, until they are edited — the program is left as the user made it.

Fields

id: String

Move

Move step id to position index among the remaining steps.

Fields

id: String

index: usize

Replace

Replace the whole program, e.g. with one loaded from a file.

Fields

program: Program

Implementations

impl ProgramEdit

pub fn summary(&self) -> String

What the edit does, in a few words — without the arguments, which can be a whole sketch.

Trait Implementations

impl Clone for ProgramEdit

fn clone(&self) -> ProgramEdit

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ProgramEdit

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ProgramEdit

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for ProgramEdit

fn eq(&self, other: &ProgramEdit) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for ProgramEdit

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
